226w tec on vid card

[msimax]

i hope someone can help me i have a swiftech 226w a64 tec in my setup i was running cpuburnin on my x2 3800 to see if i can get core 0 to do 2900 anyway
while iwas doing this temps were at 9*c. so i ran core 1 and temp slowly rised to
49*. the question is my tec overpowered and will taking the ihs off help...or will water cooling get me better temps my water is at 10*c



and who knows how to put this big of a tec on a x800??

I'm no TEC expert, but I'm pretty sure if the temp slowly keeps rising, it means your TEC is too small to get rid of that much heat from the CPU.

As for getting that big of a TEC on your X800, I'm not sure.

Can someone else shed some more light on this?

[DeltZ]

sorry not really sure how you're cooling the tec


maybe you're not cooling the tec well enough...

[Holst]

Pleasew tell us how you are powering the TEC.

Water temperatures at load and at idle.

How are you getting your water to 10*c?

[msimax]

Pleasew tell us how you are powering the TEC.= antec 550 adj psu with all wire gutted from board except 12v source

Water temperatures at load and at idle.= i dont have a probe in water but gpu is at 9-11c at idle so i assume water temp is less

How are you getting your water to 10*c?= its winter in nyc and i have my bix3 outside every thing starts to condensate

OK pic 5 i will have to find the size of the danger den mounting screws a drill and tap in the close to the center

pic 6 show the contact with just hand pressure should be better once every thing is all said and done.. now just have to find the right bit and tap


btw theres nothing in the way but have to make it air tight.anyone know where to get neoprene in nyc???

[msimax]

got me some hardware going to post results later

how come windoze shuts down when gpu hits 0c????any body quick

[Gautam]

disable the ATi services, they force a shutdown when the temp gets too low.

If I am reading this correctly you are trying to air cool the hot side of a 226W TEC and that is not going to cut it. You need to water cool the hot side.

no imeant will water cooling get better temps rather than a tec with both cores loaded that slowly climbs to 49*c

A water cooled 226-245 TEC will give lower die temps than water alone provided the cooling loop has the radiator capacity to get the heat out.

The Delta-T between the hot and cold side will be around 25C or so fully loaded (this will vary depending on CPU Freq and Vcore) and will be roughly fixed so... if you hold the hot side at 50C you will have roughly a 25C cold side. If you hold the hot side to 40C you will have roughly a 15C cold side and so on.

I don't understand the initial pictures and I can't see the ones after the closeup of the frosted base of your TEC+WB. It looks like there is a HSF on the mobo, but the waterblock+TEC is in the water cooling loop but not attached to anything.

But carrying on;

With a TEC you have a total heat burden of whatever you are cooling + the heat generated by the TEC itself. That means the water cooling system must be able to handle the combined heat burden.

Here are the most typical reasons a system like yours doesn't function properly.

#1 The PSU powering the TEC isn't strong enough for the TEC. In this case the TEC can't "pump" it's rated heat load and the TEC can actually overburden the PSU and burn it up.

#2 The water cooling system can't handle the heat burden.

#3 The TEC is just too small/weak to cool the component to begin with.

Do the math, make sure your PSU can handle the TEC. Then find out how much heat the processor you're cooling produces and makesure the TEC can handle it. Then check your radiator and make sure it is rated to dissapate the total heat burden.

its being powered by a antec 550 tc with 24a on the 12v

#2 the water in my system is next to freezing
#3 this is what i was trying to pinpoint because i have a x2 3800 and it will load to -1c at 2800mhz at 1.5-.6v the problem is when both cores are loaded the temps slowly climb to 49c .. to see if my tec was overloaded i ask the ? do people using watercooling get these temps or less to see if i should just chuck the tec and get a storm wb..

but before i got replies i started thinking of how to keep the tec so found ways to mount on my video card and it worked so now im looking to refine the mounting . im trying to get the size dangerden uses so i can find the right sized tap.. it work so well that im hold off to use with ati x1xxx gpu which uses 4 hole mount.. and im going to use the dangerden n7800 back plate to mark the holes on the coldplate since its so huge.. <a href='http://www.smileycentral.com/?partner=ZSzeb008_ZNfox000' target='_blank'><img src='http://smileys.smileycentral.com/cat/36/36_1_11.gif' alt='Thumbs Up' border=0></a> <a href='http://www.smileycentral.com/?partner=ZSzeb008_ZNfox000' target='_blank'><img src='http://smileys.smileycentral.com/cat/36/36_1_11.gif' alt='Thumbs Up' border=0></a>

Hi msimax. I have been thinking of doing the same with my X800. I have a 2x226W unit (MCW4000-T) which I have used in the past on CPU's. I think the problem you are having has really already been said, in that you don't have sufficient cooling for what you are doing. It is actually very easy to check this. Instead of using a closed loop for your cooling try an open loop. That is, run some hose line from your tap, and take the outlet from your TEC back to the sink.

[goranm]

It looks to me that your TEC is overpowered, heat transfer is too small. You need a bigger TEC. Sorry :(

[HiJon89]

I doubt your water temps are that cold with all the heat coming out of those TEC's. Even if your GPU is at -5C your water temps could still be +25C or more because the cold side of the TEC gets below ambient while the hot side adds a lot of heat to the water. With TEC's, CPU/GPU temps should be lower than water temps.

Goranm, you can't overpower a TEC. An electrical device draws power, you don't feed it. You could supply it improper voltage, but that isn't the case here as he is supplying 12V for a 12V TEC.

But this is actually academic as he changed what he is doing and solved his problems in a way. I am guessing you missed that while reading the thread ;)

[Mr. Tinker]

He meant that the heat load was too much for the TEC to cool.

[Piper]

Ahh, TY Mr.Tinker. I see that now that you mention it.

nice pics!
